【英文介绍】
The PQM II is ideal when continuous monitoring of three-phase systems is required. It provides metering power for current, voltage, active and reactive power, energy usage, power cost, power factor and frequency. Programmable set points and 4 assignable output relays allow the addition of control functions for specific applications. This includes over/under current or under voltage, unbalance, demand-based load rejection and basic alarm correction control of capacitor power factor. More complex control is possible using 4 switching inputs, which can also be used for circuit breaker on/off, flow rate and other status information
New in version 2.10:
The Voltage Interference Recorder (VDR) is used to monitor voltage dips (voltage dips) and voltage spikes (voltage surges) and can handle up to 500 dips/surges.
DNP 3.0 communication protocol standard features.
